Adjustable roller for window-curtains



EDWARD S. CLARK, OF SUFFOLK COUNTY, MASSAGHUSITS.

ADJUSTABLE ROLLER FOR WINDOW-CURTAINS.

Specication of Letters Patent No. 7,098., dated February 19, 1850.

To all whom t may concern:

Be it known that I, EDWARDS. CLARK, of the cou-nty of Suffolk and Stateof Massachusetts, have invented a new and useful Improvement inVVindow-Curtain Fixtures; and I do hereby declare that the same is fullydescribed and represented in the following specification andaccompanying drawings, letters, figures, and references thereof.

Of the drawings above mentioned, Figure l, denotes a side view of myimproved curtain roller, having the end of a curtain connected with it.Fig. 2, is a transverse sec tion of it. Fig. 3, is a longitudinalsection of it. Fig. t, is a side view of the tongue section, and itshead, as detached from the groove section. Fig. 5, is'a side view of thegroove section and its head.

In the said drawings A, is a cylindrical barrel or roller, or section,to which the curtain B, is connected, and on which it generally winds.This roller is made with the curtain edge directing head C, fixed to oneend of it, the other end being without any such fixture. It also isprovided with a groove D, extending from the head C, and throughout thelength of it, the said groove being made dovetailed in transversesection as seen in Fig. 6, which denotes a section of the barrel and itsgroove. Besides the above the barretmay be provided with a long socket,or mortise, or round hole E, extending into it, and for the reception ofa long tenon E, affixed to and projecting from the edge directing heador windlass G, of the other or tongue section H, which tongue section ofthe roller projects from the windlass head, as seen in the drawings. Thetongue section is made dovetailing in its cross section, and to fit andslide endwise into the dovetailed groove D. Besides the same, it isplowed or grooved out as seen at a, a, in Fig. 4, and at a, in sectionin Fig. 7, which denotes a cross section of the said tongue; the groovea, a being intended to receive the end of the curtain, and a wire b,around which the said curtain is wound and sewed or connected.

Previous to connect-ing the two parts composing the roller, the end ofthe curtain provided `with the wire inserted or fixed in it, is laidwithin the groove D, and close against one edge of it. The tongue H, isnext introduced endwise into the mout-h of the groove, and fixed intothe groove, and so as to completely confine the wire end of the curtaintherein, the wire preventing the curtain from being drawn out of place.

By making the curtain roller in the manner above described, it can bemanufactured of a greater length than is generally required for awindow, so that previous to being put up, or adapted to the window, theends of the tongue and groove sections, can be cut off so as to bringthe roller to the proper length for the window. Should it be desirableto employ the roller for a window a little or somewhat wider, as isoften the case, when a person removes from one house to another, the twosections of the roller may be extended a little lengthwise, so as tocarry the guide heads thereof at a little greater distance apart, thatis such a distance as may be necessary to cause the journals lto litinto their bearings or socket pieces usually applied to the window.

The lower' end of the curtain may be provided if required with a rollermade'and applied to it in substantially the same, or any differentmanner, it being understood that such roller is only to serve thepurpose, which the stick usually inserted in the lower end of a curtaindoes.

I do not claim the confining the end of a curtain or piece of cloth to aroller by means of a groove, and a strip of wood or other substanceplaced and fastened therein, as I am well aware that such is not new;but

My improvement in the construction of the curtain roller, whereby I donot only attain all the advantages of securing the cloth to it by the.groove and strip, but am enabled to regulate or adapt the roller to anywindow of any ordinary width; my said improvement consisting in makingthe curtain roller and its guide heads in two parts in such manner thatthe grooved section of the roller and one head shall be united togetherand form a separate part, while the other section or tongue, and theother head shall also be united and constitute another part, the twoparts being In testimony whereof I have hereunto set my signature thisfourteenth day of N0- vember A. D. 184.9.
